The study's purpose was to evaluate the reduction of dental caries incidence by the association of two preventive methods. 246 students of both sexes aged from 7 to 11 years registered in "Escola de Educação Básica da Universidade Federal de Uberlândia" and living in the urbana area of Uberlândia, state of Minas Gerais, were examined. The sample was distributed into two groups: children from Group 1, which received a semestral topical application of Acidulated Fluor Phosphate at 1.23% and children from Group II, that besides the topical application above related (Group I) also received weekly mouthwashes of sodium fluoride aquesus solution at 0.2%. After two years of study DMFS index were tabled and statistically analysed. It was verified a reduction of 33.97% in the incidence of dental caries (in the permanent dentition). The difference between the Groups was significant at 5% level of confidence.
该研究的目的是评估两种预防方法联合使用对龋齿发病率的降低效果。对在“乌贝兰迪亚联邦大学基础教育学校”注册、年龄在7至11岁、居住在米纳斯吉拉斯州乌贝兰迪亚市区的246名男女学生进行了检查。样本分为两组：第一组儿童接受了为期半年的1.23% 酸性磷酸氟局部应用，第二组儿童除了接受上述局部应用（第一组）外，还每周使用0.2% 的氟化钠水溶液漱口水。经过两年的研究，列出了DMFS指数并进行了统计分析。结果证实龋齿发病率（恒牙列）降低了33.97%。两组之间的差异在5% 的置信水平上具有显著性。
